Implementations§
source§impl<'a> ClientHello<'a>
impl<'a> ClientHello<'a>
sourcepub fn server_name(&self) -> Option<&str>
pub fn server_name(&self) -> Option<&str>
Get the server name indicator.
Returns None if the client did not supply a SNI.
sourcepub fn signature_schemes(&self) -> &[SignatureScheme]
pub fn signature_schemes(&self) -> &[SignatureScheme]
Get the compatible signature schemes.
Returns standard-specified default if the client omitted this extension.
sourcepub fn alpn(&self) -> Option<impl Iterator<Item = &'a [u8]>>
pub fn alpn(&self) -> Option<impl Iterator<Item = &'a [u8]>>
Get the ALPN protocol identifiers submitted by the client.
Returns None if the client did not include an ALPN extension.
Application Layer Protocol Negotiation (ALPN) is a TLS extension that lets a client submit a set of identifiers that each a represent an application-layer protocol. The server will then pick its preferred protocol from the set submitted by the client. Each identifier is represented as a byte array, although common values are often ASCII-encoded. See the official RFC-7301 specifications at https://datatracker.ietf.org/doc/html/rfc7301 for more information on ALPN.
For example, a HTTP client might specify “http/1.1” and/or “h2”. Other well-known values are listed in the at IANA registry at https://www.iana.org/assignments/tls-extensiontype-values/tls-extensiontype-values.xhtml#alpn-protocol-ids.
The server can specify supported ALPN protocols by setting ServerConfig::alpn_protocols.
During the handshake, the server will select the first protocol configured that the client supports.
sourcepub fn cipher_suites(&self) -> &[CipherSuite]
pub fn cipher_suites(&self) -> &[CipherSuite]
Get cipher suites.

source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();source§fn bright_black(&self) -> Painted<&T>
fn bright_black(&self) -> Painted<&T>
Returns self with the

set to

source§fn bright_green(&self) -> Painted<&T>

source§fn bright_white(&self) -> Painted<&T>

set to

§Example
println!("{}", value.bright_white());source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

§Example
println!("{}", value.on_bright_white());source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();source§fn underline(&self) -> Painted<&T>

§Example
println!("{}", value.rapid_blink());source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
